IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 NIM server (formerly known as NIM master) service (nimesis) could allow a remote attacker to execute arbitrary commands due to improper process controls.  This addresses additional attack vectors for a vulnerability that was previously addressed in CVE-2024-56346.

Remedy

IBM strongly recommends addressing the vulnerability by following the instructions in the fixes and remediation section of the IBM security bulletin: https://www.ibm.com/support/pages/node/7251173

Remedy

IBM strongly recommends addressing the vulnerability now.   AIX and VIOS fixes are available. The AIX and VIOS fixes can be downloaded via https from: https://aix.software.ibm.com/aix/efixes/security/kerberos_fix.tar     The link above is to a tar file containing this signed advisory, fix packages, and OpenSSL signatures for each package. The fixes below include prerequisite checking. This will enforce the correct mapping between the fixes and AIX Technology Levels.   You must be on the 'prereq for installation' level before applying the interim fix. This may require installing a new level(prereq version) first from: https://www.ibm.com/resources/mrs/assets?source=aixbp   AIX LevelInterim FixFileset Name (prereq for installation)7.2, 7.3IJ55344s9a.250722.epkg.Zkrb5.client.rte (1.16.1.7)   VIOS LevelInterim FixFileset Name (prereq for installation)3.1, 4.1IJ55344s9a.250722.epkg.Zkrb5.client.rte (1.16.1.7)   To extract the fixes from the tar file:   tar xvf kerberos_fix.tar cd kerberos_fix   Verify you have retrieved the fixes intact: The checksums below were generated using the "openssl dgst -sha256 [filename]" command as the following:   openssl dgst -sha256filename7e771a31c6f02b5635d99e3444c6085c1c67fd744ed00eade1d042134df6bb54IJ55344s9a.250722.epkg.Z   These sums should match exactly. The OpenSSL signatures in the tar file and on this advisory can also be used to verify the integrity of the fixes. If the sums or signatures cannot be confirmed, contact IBM Support at http://ibm.com/support/  and describe the discrepancy.           openssl dgst -sha256 -verify [pubkey_file] -signature [advisory_file].sig [advisory_file] openssl dgst -sha256 -verify [pubkey_file] -signature [ifix_file].sig [ifix_file]   Published advisory OpenSSL signature file location: https://aix.software.ibm.com/aix/efixes/security/kerberos_advisory.asc.sig
